“This was a precautionary landing per an indicator on the pilot’s instruments,” Cmdr. Ronald Flanders, spokesman for Commander, Naval Air Force, U.S. Pacific Fleet, told Military.com. “This was not a physiological episode. The pilot is fine. The aircraft is fine.”

He explained that the pilot executed the NATOPS procedure and deduced he was far enough away from Lemoore to call in a landing at Fresno.

According Flanders the incident was possibly related to a mechanical issue in the aircraft but did not give any further details on what the issue might be. “Maintainers from VFA-125 are inspecting the aircraft to assess why he got that indicator,” he said. “Once it is cleared for flight, it will return to Lemoore.”

NAS Lemoore is home to Strike Fighter Squadron 125, a replacement squadron, as well as VFA-147, which will be Navy’s first operational F-35C squadron.
